Okay I have 5 of 6 of these. I finished the Arena challenges available to me right now and I can't seem to find the 6th statue that opens up an area with a rainbow colored force field. Any suggestions? This is really annoying. If I knew the last one would be so difficult to find, I would have kept track of where I found each of the first 5.

Thanks!

Edit: Forget it, I found it. It was in a strange place around an arch near the beginning of the level by my spaceship. I had to go around an arch to the left, hug the wall and crouch jump into a small area and found it.
